You can keep track of the announcements with the following live stream or via our blog updates below. The conference will start at 5.30pm UK time (12.30pm ET, 9.30am PT).

19:03And that's a wrap! Some interesting announcements. Not much earth-shattering, but there's quite a bit of promise in the lineup of Xbox One games coming between now and 2015. Thanks for joining us, and stick around tonight as we'll be covering conferences from EA, Ubisoft and Sony.

18:59Phil Spencer's wrapping things up: "This is just the beginning. We will continue to invest... We will continue to listen to you, the community, and we will continue to make Xbox for you."

18:57Next announcement, exclusive to Xbox One, is a new Crackdown. Apparently, it will re-imagine open-world experiences. The trailer doesn't really show much in the way of actual gameplay, so hard to judge. There are explosions and buildings collapsing for players who love 'em.

18:54PlatinumGames' Hideki Kamiya (whose favourite game is Link to the Past) announces Scalebound for Xbox One. Looks like we should be expecting plenty of epic dragon fights, if the trailer is to be believed.

18:51Bronson joins up. The three of them head outside. There's a lot of voice chat, as the squad attempt to strategise and take out a group of enemies. "Somebody, do something!" "Good game, guys."

18:48Some teamwork's going on, as a player named Megan is taking the lead and giving the player instructions. They're making their way through an empty subway station, it seems.

18:47Massive Games' Ryan Barnard is here. Looks like he's talking about Tom Clancy's The Division. New content first for Xbox One, apparently. Here's some gameplay taking place in New York City on Christmas Day.

18:46Lobb announces this time they're rebooting Phantom Dust. Only for Xbox One. 2015.

18:44Microsoft's Ken Lobb's favourite game of all time is Crackdown, apparently. But more importantly, he's chatting briefly about Killer Instinct, which underwent a successful reboot.

18:38World premiere of the first look at the new Tomb Raider. Despite what a lot of people say, I loved the Tomb Raider reboot last year. "We become who we're meant to be," says Lara Croft. Rise of the Tomb Raider, out holiday 2015.

18:26Halo 2 is getting the anniversary edition treatment. It'll contain the original Halo 2 multiplayer "exactly as it shipped ten years ago". And then six iconic Halo 2 maps have been recreated with the power of Xbox One.

18:25Am I alone in thinking Halo 3: ODST is one of the better Halo games and is underrated?

18:23Studio head of 343 Industries Bonnie Ross is on stage. November 11 this year, you can play the entire Master Chief saga on Xbox One with Halo: The Master Chief Collection. Quite a big applause for re-releasing old games.

18:20A video look at the gorgeous Ori and the Blind Forest. And now we're onto Halo, which I guess is what most people have been waiting for.

18:17Oh, Conker's in Project Spark. That's neat, I suppose. Except, wouldn't people rather have a new Conker game instead?

18:17Trailer - Project Spark, a create-your-game type title for Xbox and PC. It looks interesting, but these sort of games have never really appealed to me. I guess I'm just not that imaginative, and would always prefer to play something designed by the developer.

18:13They wanted something to implement something "innovative", so guess what, you can play the villain, setting creatures and traps on the map, doing your best to stop the party of heroes. (Didn't Dungeonland do something similar last year?)

18:11Lionhead's David Eckelberry is showing off Fable Legends, the developer's upcoming co-operative role-playing title. They're showing off some gameplay right now. It looks pretty standard - slashing, casting and so forth.

18:08Harmonix's Alex Rigopulos announces Dance Central Spotlight, an all-new digital title exclusive to Xbox One out in September.

17:56I kind of wonder what customisation will be like for Unity. I assume there'll be some degree of it, if you're playing with friends in the same world. But anyway, the stream goes four-way split-screen as some pointy, slashy action unfolds. And then, well, a few unfortunate souls find their heads on some pikes.

17:54Gameplay time. Stabbing, mixing with crowds, scaling buildings, stealth. So far, very Assassin's Creed. Except, you're doing all of this with a few buddies.

17:52Assassin's Creed Unity time. Ubisoft's Vincent Pontbriand is talking it up. French Revolution! The game will be the first time you'll be able to form your own brotherhood with up to three friends on Xbox Live, which sounds like a neat idea.

17:50Evolve time from Turtle Rock Studios. I played this a few months back - it was fun. Definitely one for Left 4 Dead fans. They're showing a new trailer, summarising the four-versus-one concept.

17:48"Epic". "Fun". "Beautiful". "Socially connected". Out on Xbox One and Xbox 360 on September 30. And now a fancy trailer showing off some impressive visuals. Especially liking the wet weather.

17:46But enough about Forza 5. Ralph Fulton is here to chat about the sequel to the best (well, my favourite) Forza game. Forza Horizon 2 will be open-world again, and has a day-night cycle and dynamic weather, all in 1080p.

17:45Nurburgring will make its Xbox One debut on Forza 5. It will be available from today - and it's free. That's pretty awesome.

17:43More explosions. A flying piece of debris hits the player character, and it looks pretty serious. A squad member comes to his aid.

17:40Explosions. Gunfire. Mayhem. Standard Call of Duty, really. Then a swarm of drones starts attacking the squad. The player rips apart a car door and uses it as a shield.

17:38They're showing gameplay of the first-person shooter. Visually, it looks decent. The player is making his way through a ruined building and onto the street.

17:35First-up - Call of Duty: Advanced Warfare. Xbox owners will be the first to play all of the add-on content, as usual.

17:34Spencer says the fans are shaping the Xbox, mentioning feedback and the monthly updates: "We are better for it." He adds the entire presentation will be completely games-focused. Microsoft wants Xbox One to be the place for games.

17:32Microsoft's E3 2014 media briefing has begun. Head of Xbox Phil Spencer is on stage: "It's an honour to be with you today."

17:29Right, we're just a couple of minutes away from the start of the presentation. We're all ready - how about you?
